Costa Mesa homes and their backyard patios
Costa Mesa sits right next to Santa Ana, where we're based, and we do the same work here that we do back home in Santa Ana and up in Anaheim. The houses we see are mostly single-story homes with a back yard, along with townhomes and condos that have a small patio. The calls usually sound alike. Someone has a patio they barely use and wants a room they can sit in on more days of the year.
Many back yards here are on the small side, so the room usually goes where the patio already is, and that makes the patio the first thing I look at.

Our services in Costa Mesa, CA
- Patio-to-sunroom conversion
A lot of Costa Mesa back yards already have a concrete patio right off the kitchen or family room, and that's usually the easiest place for a new room. We check whether the slab can carry walls and a roof before we plan anything on it, and we tell you plainly if it needs work first.
- Patio enclosures
If you already have a patio cover you like, closing in the sides can give you a room for evenings and cooler days without starting over. We look at how the cover ties into the house and whether its posts can take walls before we put a price on it.
- Patio cover installation
Older wood covers on houses here are often worn out or sit too low to build under later. We replace them with a cover sized and attached so it can be closed in down the road if you decide you want a room.
- Sunroom construction
When there's no patio to start from, or the old one has to come out, it's a full sunroom construction job with a new base, framing and a roof tied into the house. We settle the layout, the windows and how you'll heat and cool the room before anything is ordered, since those are the hardest things to change once the walls are up.
- Four season sunrooms
Families who want a room for every month, as an office or a place for the kids, usually ask for a four season room with insulated walls and glass. We work out the heating and cooling at the start, because a glass room that gets afternoon sun can run warm if that choice is left for later.
- Sunroom remodeling
Some Costa Mesa houses already have an older sunroom that leaks, runs hot or just never gets used. We look at what's worth keeping, then replace the glass, roof panels or framing that's letting the room down.
What Costa Mesa patios ask of a sunroom
The slab or deck under a sunroom matters more than anything you'll see once it's done, because walls, glass and a roof put real weight on edges that were often poured for patio furniture. On a lot of houses here the patio is older, and how thick it is or what's under it is something I can only tell once I'm standing on it, so I check it at the estimate and tell you if it needs work first. Old patio covers get the same look, since many are attached to the house in a way that was never meant to hold up walls.
That base is also most of what moves the price, along with the size of the room and whether it's screened, glassed in or fully insulated. The schedule turns on the steps before we build: settling the design and the heating and cooling, any permit the city requires, and ordering parts once the plans are final.

Costa Mesa sunroom questions answered
Do I need a licensed contractor to build a sunroom in Costa Mesa?
Yes, in most cases, because the state licensing board requires a license whenever a job needs a building permit, uses employee labor or has contracts totaling $1,000 or more in labor and materials. A bigger job can't be split into smaller contracts to stay under $1,000, and a contractor has to hold the license before bidding. We're licensed and fully insured.
How do I apply for a building permit for a sunroom in Costa Mesa?
Building permits in Costa Mesa come from the city's Building Safety Division, and plans and applications go in online through TESSA, the city's permit system. Everything has to be entered right in TESSA, since paper forms are ignored and incomplete applications get sent back. When your room needs a permit, we prepare the plans, file with the city and meet the inspector, and we keep you posted along the way.
Can I get an Insta-Permit for a sunroom in Costa Mesa?
A sunroom isn't on the city's Insta-Permit list, which covers simple, limited jobs like re-roofs, water heaters, EV chargers, panel upgrades, HVAC and re-pipes. Each of those comes in one version for licensed contractors and one for owner-builders. To ask what your room needs, call the Building Safety Division at (714) 754-5273, and we settle that with the city before any part is ordered.
What are the penalties for unlicensed contracting in California?
A first offense for contracting without a license is usually a misdemeanor, with up to six months in jail, a $500 fine or both. An administrative fine of $200 to $15,000 can come on top of that. Those penalties land on whoever does the work, and they're a good reason to confirm a license before anyone starts on your house.
How much does a sunroom cost in Costa Mesa?
Your price comes down to the size of the room, the type you choose and the shape of the patio or deck it sits on, and I give it to you in writing after I measure. A screened or three season room costs less than a fully insulated four season room with heating and cooling, and a slab that needs work or an old cover that has to come out adds to the job. The estimate lists what the price covers, so nothing is left to guess about.
How long does it take to build a sunroom in Costa Mesa?
Most of the time on a sunroom goes into the steps before the build: finishing the design, getting any permit through the city and ordering parts once the plans are final. We don't order a part until those plans are settled, because a change after ordering is what usually stretches a schedule. When I come out, I'll walk you through which of those steps your room needs.
